Safety Information

General
Some parts of Lenze Americas Corporation controllers can be electrically live and some surfaces can
be hot. Non-authorized removal of the required cover, inappropriate use, and incorrect installation or
operation creates the risk of severe injury to personnel and/or damage to equipment.
All operations concerning transport, installation, and commissioning as well as maintenance must be
carried out by qualified, skilled personnel who are familiar with the installation, assembly, commissioning,
and operation of variable frequency drives and the application for which it is being used.
Installation
Ensure proper handling and avoid excessive mechanical stress. Do not bend any components and do not
change any insulation distances during transport, handling, installation or maintenance. Do not touch
any electronic components or contacts. This drive contains electrostatically sensitive components, which
can easily be damaged by inappropriate handling. Static control precautions must be adhered to during
installation, testing, servicing and repairing of this drive and associated options. Component damage
may result if proper procedures are not followed.
To ensure proper operation, do not install the drive where it is subjected to adverse environmental
conditions such as combustible, oily, or hazardous vapors; corrosive chemicals; excessive dust, moisture
or vibration; direct sunlight or extreme temperatures.
This drive has been tested by Underwriters Laboratory (UL) and is UL Listed in compliance with the
UL508C Safety Standard. This drive must be installed and configured in accordance with both national
and international standards. Local codes and regulations take precedence over recommendations
provided in this and other Lenze Americas Corporation documentation.
The SMVector drive is considered a component for integration into a machine or process. It is neither a
machine nor a device ready for use in accordance with European directives (reference machinery directive
and electromagnetic compatibility directive). It is the responsibility of the end user to ensure that the
machine meets the applicable standards.
Electrical Connection
When working on live drive controllers, applicable national safety regulations must be observed. The
electrical installation must be carried out according to the appropriate regulations (e.g. cable cross-
sections, fuses, protective earth [PE] connection). While this document does make recommendations in
regards to these items, national and local codes must be adhered to.
The documentation contains information about installation in compliance with EMC (shielding, grounding,
filters and cables). These notes must also be observed for CE-marked controllers. The manufacturer of the
system or machine is responsible for compliance with the required limit values demanded by EMC legislation.
Application
The drive must not be used as a safety device for machines where there is a risk of personal injury or
material damage. Emergency Stops, over-speed protection, acceleration and deceleration limits, etc must
be made by other devices to ensure operation under all conditions.
The drive does feature many protection devices that work to protect the drive and the driven equipment
by generating a fault and shutting the drive and motor down. Mains power variances can also result in
shutdown of the drive. When the fault condition disappears or is cleared, the drive can be configured to
automatically restart, it is the responsibility of the user, OEM and/or integrator to ensure that the drive is
configured for safe operation.
